phabricator: add a config knob to create obsolete markers when importing This too can get a tristate switch if desired. But if so, that needs to happen by having evolve add the option. Differential Revision: https://phab.mercurial-scm.org/D8138

phabricator: add a config knob to import in the secret phase For my use anyway, it's better to have a config knob that's always set than to try to remember a switch. But we can add a tristate switch if desired. Differential Revision: https://phab.mercurial-scm.org/D8137

phabricator: add a `phabimport` command I've had `alias.phabimport = $hg phabread --stack $1 | $hg import --bypass -` for a while now, and I suspect others do too. That's limited though, in that it can't use the information on Phabricator to restore it in the original location, so I'm making it a first class command. This doesn't do anything ambitious like that- this is mostly a simplification of `hg import` to get the equivalent of the alias mentioned above. The `--bypass` option is hardcoded to be enabled and the message about amending rejects dropped (rejects aren't created with `--bypass`), because editing patches on Phabricator seems like an unusual workflow. This will need other options, like `--obsolete` and `--secret`. I think these would be more useful as config settings, as I imagine the workflows are pretty fixed depending on roles. Reviewers who don't queue patches probably never want `--obsolete`, but may need `--secret`. Reviewers who do will want the former, but not the latter. I left `--stack` as an option, but that should probably be a config knob too (or at least default to on)- if the point of this is to avoid rejects, it doesn't make sense to skip dependencies in most cases. Evolve is going to need a fix to its wrapping of `cmdutil.tryimportone()`, as it currently assumes `opts` has an `obsolete` key. It's worked around for now.

rust: update the README with more up-to-date and thorough information Differential Revision: https://phab.mercurial-scm.org/D8274

transactions: convert changes['phases'] to list of ranges Consecutive revisions are often in the same phase, especially public revisions. This means that a dictionary keyed by the revision for the phase transitions is highly redundant. Build a list of (range, (old, new)) entries instead and aggressively merge ranges with the same transition. For the test case in issue5691, this reduces memory use by ~20MB.
